The spheres or beads illustrated in the drawings are drawn so as to appear as transparent or semi-transparent, and the contour lines depicted in the drawings depict the surface and contours of the clear or transparent flexible top surface of the pack shell, which encloses the illustrated spheres or beads. Structure illustrated in broken lines is not otherwise part of the claimed design. The stippling shown in FIGS. 2-6 depicts an opaque bottom surface. Color is not being claimed in FIGS. 1-7, and thus the opaque bottom surface could comprise any color.
